Nice article that glimpses the surface of what those modern malloc libraries do under the hood. Also, that's why I like custom allocators. There is too many (hard to control) magics happ3n behind malloc. pranitha.dev/posts/rust-a...

Your Rust Service Isn't Leaking — It Could Be the Allocator

How we diagnosed unexplained memory staying pinned near the top of our container limit in a Rust event stream processor — not a leak or fragmentation, and why the allocator matters.

meshoptimizer 1.2 is out! Featuring support for tangent generation, a significantly faster vertex decoder for Intel/AMD CPUs, several new smaller algorithms (cluster position compression, triangle filtering, clusterlod BVH) and more. GitHub stars and boosts appreciated! github.com/zeux/meshopt...

WIP galaxy renderer in Vulkan

git LFS + multiple remote mirrors are annoying - Forgejo's push mirror: does not sync large files - one remote with multiple push URLs: only push large files to the first push URL - multiple remotes: seems to work. But it's annoying since I need to `git push` multiple times for different remotes

Weekend project: "compute toy": compute shader-based Shadertoy-like thing. It uses my existing Vulkan project infrastructure, like shader hot reloading. Shader in the demo is copied from shadertoy.com/view/Xds3zN

Baby's WIP #vulkan render graph implementation. I am still working out how best to automatically generate barriers. The current heuristic is fairly coarse and may limit expressiveness.

A nice side effect of converting an old C++ project to use C++20 modules is that I no longer need to think about which header to include to use particular functions. I am using a much larger granularity for modules (one CMake target per module), whereas before I had hundreds of small header files.

Next week, we are going to start revisiting Nia Bickford's vk_mini_path_tracer tutorial! We did this tutorial in 2021, but a number of people in the meetup are interested in revisiting it and following along. www.meetup.com/graphics-pro...

someone already vibecoded (a bad clone of) this and shared it online because we live in the worst timeline y'know it kinda disincentivizes me from sharing progress when there are slop ghouls around every corner, AI or otherwise

Just set up AdGuard Home on a new Raspberry Pi for the first time. As someone who has never used a Raspberry Pi before, this whole process of assembling the case, installing the OS, and installing the software took less than 2 hours (I'd expect it to take like a whole weekend). Pleasantly surprised

I don't know. The sheer complexity of this issue (both implementations and the mental overhead of programmers) just to save a few keystrokes makes me feel it's not really worthwhile? It feels more like a fashion when the convinience is debatable? #pldev terts.dev/blog/no-semi...

Haven't done webdev for a while, and it seems (at least some) things are getting better. TIL HTML popover attribute, goodbye to all the previous hacks with an invisible checkbox + label to achieve a "no-js dropdown menu" #webdev #html

HTML popover global attribute - HTML | MDN

The popover global attribute is used to designate an element as a popover element.

Ugh. I've made the same mistake in almost all my docker-compose files. I am only saved because - I don't have any database ports exposed directly via Docker - I have an extra firewall setup at the VPS's web console akselmo.dev/posts/they-b...

TIL "falling factorial": (n)_k = n(n-1)...(n-k+1) It's interesting that n!/(n-k)! is very often seen (pick from n choices, then pick from n - 1 choices, etc), but I didn't know if it has a single notation. en.wikipedia.org/wiki/Falling...

Baby's first Forgejo actions pipeline. Can probably reduce my GitHub Actions usage substantially (the only use case not covered is for Windows runners)

We think endlessly scrolling the timeline is new? Here's a group of kids reading a wirelessly transmitted newspaper in 1938.

TIL that VS Code's SSH functionality maintains a node.js server at the remote, and the server eat 100% CPU power and RAM on my low-end VPS.

This is a pretty nice poster. The integration of vector fields and the Stokes' theorem stuff took me a while to parse, but I'd really love it if someone had presented this information to me this way before. #calculus

I've written a bunch of programming language related projects in the past, and are quite comfortable with this stuff. But if a learning resource dumps me with a BNF and hope me to magically understand the syntax of a new feature, I just can't, or at least it will take me more trouble than worth it.

Fun "temporal" bug in my new path tracer project that only manifested when I set max bounces to a very low value (e.g., 3). Can you guess why?

Sometimes it is hard to tell whether this is a human troll or the whole text is generated via LLM. Or maybe both. For context: this is a personal project that I don't expect anyone to use. Nevertheless, what this person described is completely bogus

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

No Graphics API — Sebastian Aaltonen

Graphics APIs and shader languages have significantly increased in complexity over the past decade. It’s time to start discussing how to strip down the abstractions to simplify development, improve pe...

I've built a text adventure game engine on top of the C++ Standard. Why? I have no idea. But it's a learning tool with quests and time travel and artifacts and NPC's and XP and ... well, you just have to check it out! cppevo.dev/adventure

It is interesting that many ray tracing APIs (such as Vulkan and OptiX) require 3x4 matrices (rather than 4x4) for affine transformations. Makes me wonder about many usages of 4x4 matrices waste 16 bytes to always store [0, 0, 0, 1]
